Scott Shane recently joined the New York Times as a blogger for the site's new You're the Boss blog and in his most recent post used a series of charts to show that the United States is actually becoming less entrepreneurial than we would like to pretend.
Professor Shane, a professor of entrepreneurship, has been an outspoken skeptic of entrepreneurial capitalism, casting doubt on the extent and benefits of entrepreneurship. His latest line of research concerns genetics and entrepreneurship, identifying "the influence of genetic factors on the variation across people in opportunity recognition." This, Professor Shane purports to demonstrate, is heritable and independent of environment, as are occupational choices in general, such as teacher or manager or self-employment. (For a critique of opportunity recognition, see this recent paper: Download Creative Discovery Innovations June 2009.)
Notwithstanding potential sampling errors, the heritability of personality traits is a breeding ground for questionable claims. As the eminent Samuel Bowles has pointed out, "data from modern economies suggest that personality influences individual success, but the effects are quite modest." Moreover, "the correlations between parental and offspring measures of personality are strikingly low." The world periodically endures genetic determinism fads, and they rarely end well.
Plus, if entrepreneurship is solely determined by genetic inheritance, why even have professors of entrepreneurship?
In his latest post, however, Professor Shane is onto something: whether measured by the number of new employer firms started each year or the number of new establishments, the rate of entrepreneurship has fallen over the past two or three decades. Shane uses
Census data that the Kauffman Foundation has helped fund, and I published charts on the falling establishment entry rate in
a recent paper. And the share of Americans working in giant firms (those with more than 10,000 employees) has slowly but steadily risen in the past decade.
But there are a few points Shane fails to make. As one of his commenters notes, there has been a rebound in new firm and establishment creation since 2002. One of the datasets only runs through 2005 and when new Census data are released in August, we should know whether or not this rising establishment formation trend continued. With regard to new firm creation (nb, employer firms, not self-employed consultants or personal services), Shane's data run only up to 2007. But the
Kauffman Index of Entrepreneurial Activity showed a slight uptick in new firm creation 2008. It will also be interesting to break all of this down by industry.
So what does this mean? We've actually seen a steady increase in the number of new firms started over the past few years. Shane's point is that while absolute numbers may increase, they fail to keep pace with population growth and so the rate, firm starts per capita, actually falls. That's right. But this only highlights the crucial need for more new firms, for more entrepreneurs. As
we've noted before, using that same Census data, looking back over the past thirty years, if we had taken startups out of any given year, net job creation for the overall economy would have been negative in most years. No new firms, no new jobs. No one can escape, moreover, the great lesson of economic history that entrepreneurs are disproportionately responsible for radical innovations.
But the message is much broader than this: the real source of economic growth lurking in here is firm growth. This signals market success, generates jobs, and brings with it increasing returns to ideas. So even if the rate of entrepreneurship fluctuates on an annual or decennial basis, this doesn't mean that there aren't entrepreneurial firms growing to scale during that time. This, in fact, is precisely the pattern we would expect to see: a high rate of new firm creation followed by a period of falling entrepreneurship as firms fail, consolidate, and grow. This will (or should, provided barriers to entry are kept low) be followed by yet another period of high rates of entrepreneurial activity.
